5. Antioxidantes dietéticos: controvérsias e perspectivas
The generation of reactive oxygen and nitrogen species (ROS and RNS) during metabolism is capable of damaging cellular biomolecules. To be protected against oxidative injury, cells evolved complex cellular defense mechanisms and the capability to use exogenous antioxidants to eliminate ROS/RNS. The potential role of micronutrients as antioxidants (vitamin C,
